GASTON A. GUYOT, 0F ATTLEBORO, MASSACHUSETTS.

BUCKLE.

Application filed December 24, 1924.

To all whom z' may concern.L

Be it known that I` GASTON A. GUYOT, a citizen of the United States, residing at Attleboro, in the county of Bristol and State of Massachusetts, have invented new `and useful Improvements in Buckles, of which the following is a specification.

This invention relates to certain new and useful improvements in buckles and the primary object thereof is to provide a buckle which automatically adjusts itself for use with belts of varying thicknesses, so as to enable same to be employed with extremely thin or comparatively thick belts, and any thicknesses between or intermediate of the range which the buckle possesses.

A further object of the invention is to provide a buckle of the character described which is of simple, economical and compact construction and which involves a minimum of parts which are effective and positive in operation.

In the drawings Figure 1 is a rear elevation of the invention;

Figure 2 is a section on line 2-2 of Fig. l;

Figure 3 is a section on line 3-3 of Fig. 2 and Figure 4 is a detail perspective view of the jaw.

In proceeding in accordance with the present invention, the body or front l of the buckle is provided with side flanges 2 which latter have inwardly extending ears 3 to engage and guide the free end of the belt B. A lever 4 is provided with a cut-out 4 through which the opposite end B of the belt is passed and rigidly secured thereto in any well known manner in the art. The lever 4 is provided with a substantially right angular lip 6, the latter having pintles 7 at its ends journaled in the flanges 2.

A self-adjusting or automatic cam jaw 8 is provided, the ends of which are formed with integral ears 9 that have substantially triangular openings 10 therein with curved sides 1l. The ends of the lip 6 are received in the openings 10 of ears 9 of the jaw 8 and, when the lever 4 is in operative position causes the cam or jaw to engage the belt and clamp the latter against the buckle body or front.`

Serial No. 757,911. n

From the foregoing it will be seeny that f the jaw has a range of movement, determined by the degree of the arcs l1 of openings l0, independent of the ends of the lip 6 so as to accommodate belts of any thickness falling within said range of movement determined by the degree of the arcs ll, the sides of the triangular opening engaging the lip ends and limiting movement thereof accordingly. The gripping face of the jaw 8 is preferably provided with spaced ribs 8 so as to obtain a firm grip on the belt.

Therefore the lever 4 will be seen to occupy the same relative position to the front regardless of the thickness of the belt within the range of belt thicknesses which the jaw is designed for, affording comfort in wear to the user.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is v l. In a belt buckle, a front having perforated parts a lever having pintles journaled in said parts and having a substantially right angular lip, and a swinging jaw having substantially rightv angular ears formed with substantially triangular openings receiving the ends of the lip, the jaw being movable relative to the lever and the lip ends being movable in the openings and being limited in their movement by engagement with the sides of the openings.

2. In a belt buckle, a front, a lever pivoted to the front and having an angular lip, and a swinging jaw pivoted on the lip ends in axial alinement with the pivot of the lever and having movement'independent of the lever and being engageable with the lip ends to have the extent of its swinging movement restricted thereby.

3. In a belt buckle, a front, a lever pivoted to the front, and having a lip extended radially of its pivots, and a swinging jaw having substantially right angular ears provided with openings alined with the lever pivots and receiving the ends of the lips, the openings being of a size to permit limited swinging movement of the lip therein and correspondingswinging of the jaw.

In testimony whereof I have signed my name to this specification. l

GASTON A. GUYOT.
